The most important thing you must do is to completely insulate the freezer with about 100mm of Kingspan or similar hard insulation. the more the merrier. If you had perfect insulation the compressor would hardly run at all. The insulation has to be glued on so no air can circulate between the freezer and the insulation. Leave a hole where the compressor is and the hot pipework must be outside the inulation of course.

5ghz wifi is fast but not many phones support it on tethering mode. I know this is not your situation but just for information http://support.heartv.com/miscellaneous/5ghz-devices Is a list of phones that transmit 5ghz tethering. 5gz wifi is as fast as 5g cellular data. A 5g phone with 5ghz internet tethering is a lot cheaper than that router.

Can you borrow a 5g phone just to try the video calls to see if it helps? An ethernet cable will greatly increase the speed between laptop and router. Must have for good video. A good 4g signal will support video.

5g is faster than wifi. The router will recieve the data quickly but it cannot send it by wifi to your devices as fast as it recieves it. Does your phone recieve 5g. 5g is transmitted at different frequencies that utilise much higher radio frequencies 28 ghz compared to 700 mhz - 2500 mhz for 4G so your antenna will not work.

Why on earth would you want to buy a router that receives 5g which is faster than it can transmit WiFi. 5g is about 900Mbps but standard WiFi is only about 300Mbps so whats the point.

Probably the best article I have read on whats going to happen in the future.

http://www.beginningfromthismorning.com/house-batteries-part-2/ Each battery module is 7.4v at 66ah.

Most electric car batteries are around 400v but they can be easily split and reconfigured to give you 48v say to run an inverter/charger. An electric car battery is just hundreds if not thousands of 4.2v li-ion cells. BMS circuits are available, many people are doing this for their off grid houses. Search Navitron Forum.

Your only hope is to have only ONE electric socket on board with a 0.5 amp breaker next to it. This will limit the power to charging laptops, phones etc. You need a small full sine wave inverter with standby function so it only comes on when there is a demand and buy a 24v fridge. Those batteries are useless change them for Forklift batteries. You need 12 large forklift batteries to give you a 24v system. Forklift batteries do not die like "deep cycle" batteries, they are much mor forgiving. I used to install and maintain off-grid rental properties on the Greek islands where the battery banks would weigh 8 tons and be charged by enormous truck engined diesel generators along with over 100 solar panels on each property. Villas with swimming pools.

Your perfect Concept Battery system would be a Li-Ion battery bank from an electric car. These hold around 50kwh+ of power, enough to run a narrowboat for a week. This could be charged by a 50kw generator coupled to the engine in an hour. Just imagine only running the engine one hour once a week. Of couse most engines could only run a 10kw generator but this would still only need to be run for an hour or two every 3 or 4 days. 14hp is about 10kw. Of course a proper generator would need to be coupled to the engine with a clutch system at a 1 to 1 ratio running at 1500 rpm. Batteries from crashed electric cars are available for a couple of thousand and generators are cheap. Lets see who will be first to build it???

I see what you mean. I meant the amp/hour rating of the battery is not fixed, it can fluctuate from the manufacturers specification.

Yes, because the battery is only 100Ah at a discharge rate of 5 amps. At a discharge rate of 50 amps it becomes about a 40Ah battery and going the other way at a discharge rate of 1 amp it will be come a 150Ah battery. https://www.batterystuff.com/kb/tools/calculator-sizing-a-battery-to-a-load.html If you enter 50 amps for 1 hour you will see you need a 236Ah battery. Tick the box if your battery is more than six months old.

Everyone is forgetting that a 100Ah battery is only rated 100Ah at what they call a C20 Discharge Rate. In other words the power held by the battery when it discharges over 20 hours or at 5 amps. When you discharge a battery quickly or at any rate over the C20 rating the battery loses power much quicker and the amp/hour rate drops dramatically.. 200 amps from 4 batteries means 50 amps per battery which would probably only last 10 minutes. https://batteryuniversity.com/learn/

If you are starting from scratch you should seriously think about a 24v system using forklift batteries and 24v inverter. Uses half the amps. Can be easily charged using a truck or bus alternator.

They are very similar probably wouldn't make any noticable difference, whats more important is what controller are you using? Will it take panels in parrallel, double the amps.

The most ridiculous thing to all this is 1 horsepower is 740 electrical watts. Thats 53 amps charging your 12v battery. Running a 30 odd horsepower engine at only half a horsepower is madness. Why cant someone invent a simple diesel to 12v electricity machine, they would be a millionaire overnight.

You need a Pure Sine Wave inverter. Most fridges dont like modified sine wave. Even though you bought it from a store and payed more inside it is the same as all the others.

An alternator has 3 static windings inside and uses 6 diodes to turn the AC into DC. If some of the diodes have burnt out you will get lower output. The only way to test this is to open up the alternator.

I would buy 6 Large 1000ah forklift batteries they will last for years and deliver the current you require. Better still I would buy 12 and use a 24 volt inverter.

you need a 24v system not 12v.
